Vermont Gage 112215740 Class Zz Minus Plug Pin Gage 15.74mm

Product Description

The VERMONT GAGE 112215740 is a Class ZZ minus plug pin gage machined from steel and sized to 15.74 mm diameter. It is designed for NoGo inspection work, providing a precise go/no-go measurement reference to verify that a bored or reamed hole does not exceed its upper tolerance limit. The gage holds a tolerance of 0.00508 mm, making it suitable for quality control applications where tight dimensional verification is required. At 2 inches in overall length, it is compact enough for bench use and field inspection alike. Each unit ships with a Certificate of Accuracy traceable to NIST standards.

This plug pin gage is used in manufacturing, machining, and metrology environments to verify hole diameters during incoming inspection, in-process checks, and final inspection. It is also appropriate for setting and calibrating micrometers, verniers, and other precision measuring instruments. Typical users include quality control technicians, tool-and-die makers, machinists, and metrology lab personnel working with metric-dimensioned components.

Key Features

• Class ZZ minus tolerance classification for NoGo inspection applications
• 15.74 mm diameter with 0.00508 mm tolerance for tight dimensional control
• Steel construction for durability and wear resistance during repeated use
• 10 micro coating/finish to protect the gage surface and maintain accuracy
• Includes Certificate of Accuracy with NIST traceability for audit and calibration records
• Compact 2-inch overall length suited for bench and field inspection

Compatibility

Designed for use in NoGo hole inspection routines and as a reference standard for setting micrometers, verniers, and other precision measuring devices requiring a 15.74 mm metric reference.

Installation Notes

Plug pin gages require no power source and are handled by quality control or metrology personnel following standard gage-handling practices. Keep the gage clean and lightly oiled when stored to prevent corrosion. Do not force the gage into a bore; improper insertion can damage both the gage and the workpiece. Store in a protective case away from temperature extremes to preserve calibration integrity.
